Abstract (en)

The method involves disposing a network of light transmitters in rows and columns, where the transmitters are light emitting diodes (LED). The rows of transmitters are divided into N groups which are different from each other by a row, where different rows of each group are adjacent. The transmitters of all the rows of each group are simultaneously selected by a selection unit. An adapted signal is generated by an addressing unit for driving the emission of the transmitters according to a video data of pixels or sub pixels.
